Special Authority requests can now be submitted online. It's simple and quick!

Biosimilar transition initiative

PharmaCare is changing coverage of denosumab for osteoporosis. To maintain PharmaCare coverage, patients currently covered for the originator demosumab biologic product, Prolia^®, must, in consultation with their prescriber, switch to the approved biosimilar product, Jubbonti^®.

Prescribers may request a list of their patients prescribed Prolia brand of denosumab, so they can contact them to start the switch to Jubbonti^®.

August 29, 2024

All new Special Authority (SA) requests, including renewals, for denosumab will only be approved for Jubbonti.

August 29, 2024 to March 3, 2025

During the six-month transition period, patients with PharmaCare coverage for the originator denosumab (Prolia) who wish to maintain their coverage must transition to the biosimilar denosumab (Jubbonti). A new SA request is not required until the next scheduled renewal date (if applicable). To maintain patients' coverage, prescribers must write a new prescription for their patients on the originator denosumab (Prolia), indicating the transition to biosimilar denosumab (Jubbonti).

March 4, 2025

The originator denosumab (Prolia) is no longer an eligible PharmaCare benefit and only biosimilar denosumab (Jubbonti) is authorized for continued coverage.

SA requests for patients who are unable to transition to biosimilar denosumab will be considered on an exceptional case-by-case basis.
